Proven Interoperability

Powered by Apache Axis2, Apache Rampart and Apache Sandesha2, the Application Server has proven interoperability with major Web Services stacks including Microsoft .NET WCF.

Data Services Support

Data in either a database or file system is easily service-enabled. Business applications can be directly layered on top of the data using this approach. It may be against the organizational security policies to expose the complete database hosted within the organization. In such a scenario, only a required subset of information can be exposed to the outside world as Web services.

Visualization of Axis2 Message Flow Handler Chains

Useful when developing and troubleshooting of Web services.

Provisioning capability

Because of the modular, OSGi-based Carbon platform, any WSO2 Carbon-based product can be easily extended by installing additional Carbon components in a simple, point- and-click deployment.
